RAILROAD-SPIKE.

Specification of Letters Patent.

Patented Jan. 28, 1913.

Application filed September 12, 1911. Serial No. 648,844.

To all whom it may concern.

Be it known that I, BENJAMIN 0. Dinner, a citizen of the United States,residing at Taylors Store, in the county of Franklin and State ofVirginia, have invented new and useful Improvements in Railroad- Spikes,of which the following is a specification.

This invention relates to certain novel improvements in spikes forrailway rails.

In carrying out my invention it is my purpose to construct a spike,primarily intended for use upon railway rails, having an upper portionenlarged and formed with substantially V-shaped extensions arranged uponthe sides of the reduced center depending portion, the said upperportion being thus rendered stronger than the dependimg portiontherefore offering a greater resistanee for the withdrawal of the spikeor the accidental movement thereof due to the rolling stock passing overthe rails.

I also aim to provide a spike of this class having a central reducedportion extending below the enlarged portion, the sides of the enlargedport-ions being sharpened to form wedge members, and the said wedges,when driven within the tie, being adapted to force the material of thetie downwardly so as to force the said material tightly against thesides of the reduced portion so that the material centered by the wedgeshaped sides of the enlarged portion of the spike will be packed aroundthe reduced extension of F the spike to prevent the accidentalwithdrawal of the spike.

lVith the above recited objects, and others of a similar nature in view,the invention resides in the novel construction of spikes hereinafterfully described and claimed.

In the drawings,-Figure 1 is a side ele\'a tion of a spike constructedin accordance with the present invention. Fig. 2 is a front elevation ofthe same. Fig. 3 is a rear elevation of the same.

Referring now to the drawings in detail, the numeral 1 designates aspike proper. The spike is provided with the usual head 2, whichoverlies the front face of the said spike. The upper portion of thespike, di rectly below the head, is of a width greater than that of theordinary spikes, as is the head of the said spike. This enlargedportion, designated by the numeral 3, is, however, of a thicknesscorresponding with the thickness of a centrally arranged dependingportion 4. The portion 4 is of course integrally formed with the spikeproper, and the said depending portion adjacent its lower edge isbeveled in opposite directions. as designated by the numerals 5 so as toprovide an entering point for the spike. The enlarged portion 3 has itsside walls formed with substantially V-shaped wedge extremities havingtheir points terminating centrally of the sides of the extension 4-, andat a suitable distance away from the entering points 5 of the saidcentral portion or extension.

By an arrangement as above described, it will be noted that the enlargedportion 3 being of a greater width than the extending portion 4 is ofcourse of a greater strength than the said extension, and that the wedgeshaped portion 6 of the said enlarged portion 3 divides the materialwithin which the spike is inserted and forces the said divided materialtightly against the sides of the extension 4 so as to firmly embed allof the portions of the spike within the said material, and to preventthe accidental removal of the spike.

Having thus fully described the said invention. what I claim is:

.A. spike having a substantially rectangle lar body. said body beingprovided with a central depending. rectangular stem which has asubstantially V-shaped end, and the sides of the body at its juncturewith the stem being inclined inwardly toward each other and integrallyconnected with the said stem.

In testimony whereof I aflix my signature in presence of two witnesses.
